Public servants are pointing to problems processing Labour's so-called "baby bonus" payments as one reason for going on strike as Acting Prime Minister Winston Peters calls on workers to understand the Government has a limited purse.
The "Best Start" payments of $60 week for parents of newborn babies were designed by Prime Minister Jacinda Ardern when she was in Opposition in 2014 and are due to begin from July 1 as part of the Government's Families Package.
Inland Revenue staff are pointing to problems processing those payments as one of the factors in going on strike later this month as they seek higher pay, saying they had to be processed manually which was adding to the workload.
More than 4000 Inland Revenue Department and Ministry of Business, Innovation and Employment staff are set to strike for two hours on July 9 and July 23.
The notice of strike action comes as nurses also prepare to strike next month and teachers and principals are voting on whether to take industrial action in August.
